GLUTCEE *EEC'" Application filed Zanuzar 27. 1919.

'0 all whom it may concern:

Be it known that I, VVILFRID Josari-I Osihnn LAVALLEE, residing at 188 Christophe Colomb, in the. city of Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Clutch Mechanism; and I do hereby declare that the following is a full, clear, and eX act description of the same. 7

The present invention relates to improvements in clutch mechanism for connecting and disconnecting a cream separator with and from a motor or engine.

The main object of the invention is to pro-' vide an attachment of this character whereby a continuou rotation of the separator may be obtained direct from the engine without altering or modifying their shape.

A further object is to provide a driving connection of the character indicated, which may be uncoupled to stop the separator by a simple mechanical device Another object is to devise an attachment of this character that n y be applied for many purposes other than for operating a cream separator, as well as being of a simple construction and particularly cheap to man ufacture. i

The invention will be better understood with the aid of the accompanying draw- Fig. 4 is a top view, of the operating shaft.

Fig. is a front view of the operating clutch member.

Fig. 6 is a side view of the clutch member.

Like numerals of reference indicate cor responding parts in each figure.

In the drawings 1 is an internal combustion engine and 2 is a fly wheel mounted on the crank shaft 3 and which is provided with an outward projecting threaded hub 4. Threaded on said huh 4 is a tubular casing The said casing 5 is provided in turn, with an axially disposed hub or collar 6, the bore of which receives a shaft '8 which projects within the casing 5 and is arranged in line with the crank shaft 3, said shaft 8 being threaded at this end and provided with two slots 9 and 10 at a convenient dis- Specification of Letters Patent.

tance from one another and with an intermediate threaded portion 11 between them. The other end of the shaft 8 terminates in an eriargcd p ion 12 provided with a transverse hole in which is inserted a locking pin 13. The'shaft 8 is also centrally bored at 14 to receive the push rod 15 which is normally positioned between the two slots 9 and 10.

inside the casing 5 mounted on said shaft 8 is provided a clutch member .16 in the form of a friction disk which is adapted to abut against the inner end of the casing i8 is a hole provided in the hub of this disk or. member 16 to recelve the pin 19 which passes "ough the slot 9 in the shaft 8, thereby tiring said clutch member 16 on said shaft and permitting it to have merely a limited iding movement. On the inner end of is threaded a flanged head or 21 is a spiral spring around abutting at one end against and at the other end against the clutch member 16, therebv normally holding said clutch n ember in frictional enagemcut with trio ca g Z2 is the clutch pera-ting niem co isting ofa disk havmg a recessed face 23, said disk being centrally bored and threaded to engage the threaded. portion lion the shaft The recessed portion 23 of the disk receives in it a cross pin 24; which passes through the slot 10 but has a longitudinal movement limited by the said slot 10.

It will readily be seen that on turning the member in the proper direction it will move forward along shaft 8, carrying with it the pin 2st which is thereby brought in contact with the rod 15 and pushes the same ahead. The rod 15 on being pushed for ward will engage the pin 19 and carry the clutch 16 out of engagement with the casing 5, the same time compressing the spiral spring 21. When the clutch is not engaged with the it is evident that the said casing will turn loosely on shaft 8. In performing the reverse operation the shaft 8 is made to turn with the casing 5.

at the outward end of the shaft 8 is provided a hollow shaft 'or sle re 26; and 27 a rod secured to one end of said sleeve 26 by the pin 28. The other end of said sleeve 26 slides over the enlarged portion 12 of shaft 8 and is maintained in position by pin 13. Said rod 27 is provided with a ratchet casing 29 at its other end; and 30 is a ratchet terminai screwed to the driving pinion on the C 'eam separ tor.

The object of the ratchet connection between the rod 27 the driving pinion of to prevent abrupt ne separator.
